reattach flex circuit to Game Boy screen

A common problem with game boys is dead lines on the screen. I've seen some crude methods used (applying a non-temp controlled solder iron on the connector) but this doesn't seem to work for horizontal lines. After looking around I found these:

So some kind of anisotropic conductive material to reattach the connector might be a solution? My question is, has anyone ever attempted this on a game boy or other handheld? Or does anyone know of another solution?
Maybe solder paste + hot air would work?

How is the ribbon originally attached to the screen? Solder or some conductive glue?

Look forward to hearing your thoughts!

 

if you plan on trying something like this, I'd suggest testing the idea on some old crappy lcd panels that use a similar method to be attached, lie out of a calculator or clock...

 

Yeah, probably a good idea. When I look this up on youtube, they always use this fancy machines that provide an even and controlled pressure and temperature. So doing this by hand is probably easy to screw up. I was just curious if someone had actually had a go at it before. At least I have a hakko fx888d to provide even temp. Maybe if I clamp down some tin foil over the connector and heat that up so I can get both evenly distributed heat and some pressure.

 

I'd say a rework hot air or IR with a custom nozzle, for an iron I think you can get flat blade tips big enough to cover the whole flex...
